Numerical Study of Boundary Layer Flow and Heat Transfer of Oldroyd-B Nanofluid towards a Stretching Sheet

In the present article, we considered two-dimensional steady incompressible Oldroyd-B nanofluid flow past a stretching sheet. Using appropriate similarity variables, the partial differential equations are transformed to ordinary ( similarity) equations, which are then solved numerically. The effects of various parameters, namely, Deborah numbers beta(1) and beta(2), Prandtl parameter Pr, Brownian motion N-b, thermophoresis parameter N-t and Lewis number L-e, on flow and heat transfer are investigated. To see the validity of the present results, we have made the comparison of present results with the existing literature.
